Inclusion Criteria:

• Patients with histologically confirmed Stage IIIB, IIIC or IV unresectable or metastatic melanoma except uveal melanoma, who must have a history of treatment (chemotherapy, molecular targeted therapy, or anti PD-1 antibody therapy).

• Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2.

• Patients must have adequate organ function, defined as

  • Total bilirubin levels ≤ 1.5 x upper limit of normal [ULN] (except for patients with Gilbert's Syndrome, who must have a total bilirubin of less than 3.0 mg/dL)
  • AST/ALT levels ≤ 2.5 x ULN, or ≤ 5 x ULN if liver metastases are present.
  • Creatinine ≤ 1.5 x ULN or creatinine clearance (calculated) ≥ 60 mL/min/1.73 m^2 for patients with creatinine > 1.5 x ULN.
  • Absolute neutrophil count ≥1,500/µL and
  • Platelet count ≥ 75,000/ µL
• Men and women of childbearing potential must agree to use adequate contraception from the time of consent through 30 days after final study treatment.
• Females of childbearing potential must have a negative urine or serum pregnancy test within 1 week prior to start of treatment.
• Patients must be able to understand and willing to sign a written informed consent document.

Exclusion Criteria:

• Patients who were previously treated with ipilimumab by intravenous infusion.
• Patients receiving chemotherapy or molecularly targeted drug or anti-PD-1 antibody treatment or radiotherapy or immunotherapy within 4 weeks prior to initiating study treatment.
• Patients with a history of Grade 4 adverse events caused by chemotherapy, molecularly targeted drug, anti-PD-1 antibody treatment, radiotherapy or immunotherapy conducted more than 4 weeks prior to TBI-1401(HF10) treatment, or presence of such adverse events of Grade 2 or greater, except alopecia and adverse events controlled by a treatment.
• Patients receiving anti-herpes medication within 1 week prior to initiating TBI-1401(HF10) administration, except local treatment such as ointment.
• Patients with a history of significant tumor bleeding, or coagulation or bleeding disorders.
• Patients with target tumors that could potentially invade a major vascular structure (e.g., innominate artery, carotid artery), based on unequivocal imaging findings.
• Patients with Grade 2 or greater neurologic abnormalities (CTCAE version 4.0), including Grade 2 or greater peripheral neuropathy caused by previous treatments.
• Patients with clinically evident Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV), Hepatitis C virus (HCV), or Epstein-Barr virus (EBV) infection.
• Patients requiring systemic glucocorticoid (except 10 mg/day/body prednisolone or less) or immunosuppressive therapy because of the presence or history of autoimmune disease (e.g., Crohn's disease, ulcerative colitis) or other diseases.
• Concurrent use of any other investigational agents within 4 weeks prior to initiating study treatment.
• Patients with active CNS metastases or carcinomatous meningitis, except patients with CNS lesions that have been treated and have no evidence of progression in the brain on CT/MRI for ≥ 3 months.
• Pregnant or breastfeeding women (excluding the case in which breastfeeding is discontinued and will not resume it); women desiring to become pregnant within the timeframe of the study are also excluded.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements, as determined by the investigator.
